Abstract (en)
[origin: EP0770809A1] A coupling for coupling hoses comprising a pair of coupling main bodies (1a, 1b) that are structurally identical and undiscriminable for male and female. Each of said coupling main bodies (1a, 1b) is provided at the front end surface with a sealing surface (6) for mutual abutment and at the front end with a plurality of engaging projections (8) and engaging recesses (7), each of said engaging recesses (7) being arranged between any two adjacent engaging projections (8), so that the engaging projections (8) and the engaging recesses (7) of the two coupling main bodies (1a, 1b) can be complementarily engaged with the corresponding engaging projections (8) and engaging recesses (7) of the other coupling main bodies (1b, 1a). The engaging projections (8) are provided with respective hooked anchor sections (9) that are peripherally engaged to restrict axial movement and consequently couple the pair of coupling main bodies (1a, 1b). <IMAGE>
